'SPECIFICATION forming part of Letters Patent No. 740,018, dated September 29, 1903. Application led March 26, 1902. Serial No- 99,989. (No model.)

fo all whom it may concer-n,.-

Beit known that I, ALFRED H. HUMPHEE Y, a citizen of the United States, residing at the city of Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Gas- Ifamps, of which the following is a specilica`` ers which are embraced in a globe and used 'pss in connection With a pilot-light and the meansl for actuating the same. Y

Further objects will definitely appear in the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

My invention is clearly defined,and pointed out in the claims.

A structure embodying the features of my.

invention is clearly illustrated in the accompanying drawings, forming a part of this specication, in which'- Figure 1 is a detailed side elevation view of a structure embodying the' features of my invention, portions being shown in section' to show the arrangement of the parts. Fig. 2 is a detailed sectional viewof the attacl1- ing means for supporting the globe-holder and casing. Fig. 3`is an inverted plan ofthe globe-holder and its connections to the bottom plate F.

In the drawings similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A represents a gas pipe, which also serves as a support for the lamp or burner. A depending pin is secured to the lower end of this pipe, and to this pin is secured a plate F, which is perforated or has openings therethrough to permit the passage of air and the operating-chains et a' a",which operate the valves of the lamp. The plate F is provided with a circular iiange at the top. The casing F is adapted to pass over the plate F and is lformed at its lower end to embrace the iiange thereon. This casing or globe-support is slotted at-J J. On one side of plate F is a pin I', adapted to engage a slot J. On the opposite side is ahook-shaped pin I, adapted to engage the opposite slot J. This pin can be turned up, so as to clamp the edge of the casing and vhold it securely in position, a

spring t being provided to put tension on thev same. The top of the casing F is formed to receive and support the casing of the globe.

VWithin the casing F are arranged the burners B', which may be of any desired pattern,

being here illustrated as the Bunsen type and intended to be used in connection with mantles. The burners are connected by lateral arms or pipes B, as clearly appears in Fig. 1.

A'valve is provided in the coupling A at the `bottom of the pipe A for controlling the admission of gas to the burners. This valve is `provided with a cross-arm C', to which are secured the chains a a for the purpose of actuating the same. Above the main valve is a connection D to the gas-pipe E with the upper part of the coupling A'. This is provided with a valve D, and beyond this valve is a small vertical tip or pipe E, provided with suitable pilot-burner tip, as E', at the top. To the arm r on the' valve D is secured a coiled spring S, to the lower end of which is secured the operating-chain a. But brief mention is made of these parts-that is, the valve feature and operating mechanism and pilot-light constructionas they are fully described in Letters Patent No. 696,640, issued to me the 1st day of April,`1902.

From the foregoing descriptionit is appar- 'ent that when it is desired to remove the globe for any purpose, such as replacing mantles or adjusting the burners or valves, the same may be quickly andreadily done Without disturbing any of the connections for the valves or burners and that the same may be quickly and readily replaced.

I have illustrated and described my structure in detail; but I am aware that it is capable of considerable variation Without depart- IOO ing from my invention. For instance, a great variety of retaining means for the casing will readily suggest themselves to those skilled in the art to which my invention appertains.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a burner, the combination of a central support A; a perforated plate F having an upwardly-turned iiange at its outer edge carried by said support; a globe-supporting casing F, adapted at its lower end to embrace said flange and having suitable notches therein; pins on the said plate adapted to engage said notches; a spring-clip carried by said plate adapted to engage said casing and lock the same in position; a burner and a pilotlight within said casing; burner and pilotlight valves Within said casing; and operating-chains for said valves arranged through the perforations in said plate, all coacting for the purpose specified.

2. In a burner, the combination of a central support A; a plate F having an upwardlyturned flange at its outer edge carried by said support; a globe-supporting casing F', adapted at its lower end to embrace said ange and having suitable notches therein; pins on the said plate adapted to engage said notches; a

spring-clip carried by said plate adapted to engage said casing and lock the same in position, all coacting for the purpose specified.

3. In a burner, the combination of a central support; a perforated plate carried thereby; a globe-supporting casing adapted t0 embrace said plate at its lower end and having suitable notches therein; pins on said plate adapted to engage said notches; a spring-clip adapted to engage said casing and lock it in position; a burner and a pilot-light within said casing; burner-valves within said casing; and chains for operating said valves arranged through the perforations in said plate, all coacting for the purpose specified.

4. In a burner, the combination of a central support; a plate carried thereby; a globesupporting casing adapted to embrace said plate at its lower end and having suitable notches therein; pins on said plate adapted to engage said notches; a spring-clip adapted to engage said casing and lockit in position, all coacting for the purpose specified.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
